Un changement dans la séquence d’ADN
C'est quoi une mutation?
100
How well an organism is able to survive and reproduce in its environment
What is fitness?
100
This person wrote On the Origin of Species after a long voyage to the Galapagos Islands
Who is Charles Darwin?
100
Preserved remains of ancient organisms
What are fossils?
100
The concept that organisms that are best suited to their environment will survive and reproduce
What is natural selection?
200
Un trait héréditaire qui aide un organisme à mieux survivre et se reproduire dans son environnement
Qu’est-ce qu’une adaptation ?
200
When humans breed organisms for specific features
What is artificial selection?
200
An organism's adaptation to blend into an environment and stay undetected
What is camouflage?
200
When an entire species dies out completely
What is extinction?
200
A change in a species population distribution where traits towards the average are favored, and extreme traits provide a disadvantage.
What is stabilizing selection?
300

Qu’est-ce que la structure vestigiale ?
300
Has similar functions but different structures and do not share a common ancestor 
What are analogous structures?
300
An organism's unique sequence of DNA, usually a combination of two alleles.
What is genotype?
300
The expression of an organism's genes (observable characteristics)
What is phenotype?
300
Has similar bone structures and a common ancestor
What are homologous structures?
400
When a species separates into 2 groups that are geographically isolated from each other, creating 2 separate species
What is allopatric speciation?
400
A sharp decline in a population's genetic variation due to outside forces or random events
What is the bottleneck effect?
400
A change in population distribution of a species where one extreme trait is favored over the average
What is directional selection.
400
When adaptations of one species cause similar adaptations in another species, often found in species with symbiotic relationships, or parasites
What is coevolution?
500
The evolutionary diversification of a single ancestral line where organisms display different adaptations in response to different selection pressures
What is adaptive radiation?
500
A change in population distribution where two extreme traits are favored over the average, often a precursor to speciation
What is disruptive selection.
500
No selective pressures modify the distribution of traits in a species makes this kind of distribution
Normal distribution, normal curve, or bell curve
500
The process where organisms that are not closely related develop similar traits as adaptations to similar environments
What is convergent evolution?
500
Organisms moving from a population of one species to a separate population of the same species, changing the allele frequency or introducing new traits
What is gene flow
